post heating वाक्य

After dealing with post heating at the same deposit temperature , the average of transmission and reflectance of the films are smaller than unannealed ones but eopt is enlarged
The photoluminescence of the thin films without post heating shows that the increasing of the deposit temperature decreases the pl intensity . only the sample deposited at 450 has one evident luminescence band found nearby 523 . 2nm
The photoluminescence of the thin films without post heating is weak . only one luminescence band is found nearby 473nm . two luminescence bands are found after post heating , nearby 493nm and 368nm respectively . the intensity of the luminescence bands increase little by little when the temperature and the time of post heating continues to increase
